Its widespread adoption has turned into an incentive for malicious actions that, by exploiting GNSS vulnerabilities, aim at either disrupting or precisely modifying the PNT computation. Authenticating the GNSS signal at both the ranging and data levels is a proper way to detect and/or mitigate such threats. This article discusses the design drivers for GNSS authentication, reviews the predominant navigation message authentication proposals for a GNSS open service, and proposes a novel scheme based on the amortization of digital signatures.

From Data Schemes to Supersonic Codes : GNSS Authentication for Modernized Signals / Oscar Pozzobon in Inside GNSS, vol 10 n° 1 (January - February 2015)  

Public [article]  inInside GNSS > vol 10 n° 1 (January - February 2015) Titre : From Data Schemes to Supersonic Codes : GNSS Authentication for Modernized Signals Type de document : Article/Communication Auteurs : Oscar Pozzobon, Auteur ; Giovanni Gamba, Auteur ; Matteo Canale, Auteur ; et al., Auteur Année de publication : 2015 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géodésie spatiale [Termes IGN] authentification [Termes IGN] leurrage [Termes IGN] signal GNSS Résumé : (auteur) The problem of GNSS signal authentication is expected to draw ever more attention in an operational environment that poses a growing risk — and consequences — for “spoofing” attacks. A team of researchers present an overview of the requirements and methods for verifying the authenticity of the signals and introduce a novel scheme for authentication of open GNSS signals using supersonic codes.

Appreciative GIS and strength-based community change / Paddington Hodza in Transactions in GIS, vol 18 n° 2 (April 2014)  

Public [article]  inTransactions in GIS > vol 18 n° 2 (April 2014) . - pp 270 - 285 Titre : Appreciative GIS and strength-based community change Type de document : Article/Communication Auteurs : Paddington Hodza, Auteur Année de publication : 2014 Article en page(s) : pp 270 - 285 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Systèmes d'information géographique [Termes IGN] authentification [Termes IGN] système d'information géographique Résumé : (Auteur) Problem-solving is embedded deeply in the digital DNA of GIS. Most projects involving GIS 1.0 and 2.0 raise community weaknesses, failures and other problems and use them to motivate change. The projects often create a future that does not differ greatly from the past or last long. Although looking into community problems is important and sometimes necessary, the steps of problem-solving do not always leave people feeling happy. To inspire communities to create change based on their strengths and achievements, and to provide better participant experience, this article develops the concept of a new form of GIS called Appreciative GIS (AGIS). AGIS are grounded in the affirmative premise that every community, however challenged, is gifted with certain assets, potentials and strengths which, when effectively exploited, can take that community to a better and sustainable future. Based on Earth's internal structure, the article develops a useful layered community model where crust, mantle and core strata represent the community's body, life-draining and life-giving elements in that order. The model helps explain the different views of the community from current GIS and AGIS perspectives. A Total GIS (TGIS) cube is also developed and used to indicate that current GIS commonly focus on elements of the mantle or what we do not have, what we cannot do and what makes us weak. AGIS, on the other hand, dig up the core and cultivate what we have, what we can possibly do and what makes us strong. In a significant departure from the linear approach of problem-solving, the article suggests implementing AGIS through a 7G cyclical method. The article contends that although AGIS may not be the whole enchilada, they can serve as a beacon of hope and a powerful source of inspiration especially for individuals and groups who are perceived or made to perceive themselves as dysfunctional, weak or poor.

Cooperative GNSS authentication: reliability from unreliable peers / Liang Heng in Inside GNSS, vol 8 n° 5 (September - October 2013) 

Public [article]  inInside GNSS > vol 8 n° 5 (September - October 2013) . - pp 70 - 75 Titre : Cooperative GNSS authentication: reliability from unreliable peers Type de document : Article/Communication Auteurs : Liang Heng, Auteur ; Daniel Work, Auteur ; Grace Xingxin Gao, Auteur Année de publication : 2013 Article en page(s) : pp 70 - 75 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Navigation et positionnement [Termes IGN] authentification [Termes IGN] corrélation croisée normalisée [Termes IGN] signal GNSS Résumé : (Auteur) Secure, reliable position and time information is indispensable for many civil GNSS applications such as guiding aircraft, tracking freight, synchronizing power grids and cellular networks, and time-stamping financial transactions. This article introduces a cooperative signal authentication architecture in which civil GNSS signals, as well as the encrypted military signals on the same frequency, are sampled by a user receiver and several ad-hoc cross-check receivers at the same time. Cross-correlation of these sampled signals is used to authenticate the signal received by the user receiver.

Getting at the truth: A civilian GPS position authentication system / Z. Li in GPS world, vol 24 n° 1 (January 2013)

Public [article]  inGPS world > vol 24 n° 1 (January 2013) . - pp 67 - 73 Titre : Getting at the truth: A civilian GPS position authentication system Type de document : Article/Communication Auteurs : Z. Li, Auteur ; Demoz Gebre-Egziabher, Auteur Année de publication : 2013 Article en page(s) : pp 67 - 73 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Navigation et positionnement [Termes IGN] authentification [Termes IGN] positionnement par GPS [Termes IGN] précision du positionnement Résumé : (Editeur) [...] Which brings us to GPS. When a GPS receiver reports its position to a monitoring center using a radio signal of some kind, how do we know that the receiver or its associated communications unit is telling the truth? It’s not that difficult to generate false position reports and mislead the monitoring center into believing the receiver is located elsewhere — unless an authentication procedure is used. In this month’s column, we look at the development of a clever system that uses the concept of supplicant and authenticator to assess the truthfulness of position reports.
